Hi,
I'm currently responsible for maintaining the Seam/Wicket integration for
the Seam team. Seam maintains a "conversational" context, a session-based
map that is keyed by an id associated with a set of requests. Previously
the wicket integration worked by wrapping every redirect or outgoing url and
adding the conversation id as a parameter, and then restoring the
conversation based on that parameter in a servlet filter. While this works,
it's ugly, and doesn't play with with various URL coding strategies.
So instead, I've been working on storing the conversational id in Page
metadata. I did this by providing a new WebRequestCycleProcessor subclass
which in resolve() looks for IPageRequestTarget or
BookmarkablePageRequestTarget, pulls the page out, and restores the
conversation if the parameter is present in metdata. Correspondingly, in
respond(), I do the inverse.
This works great when running in-container, but isn't playing well with
tests that use ajax. When an ajax link is clicked in-container, the full
request cycle is step()ed through. But BaseWicketTester.clickLink(), which
I presume is the appropriate thing to use, does:
AjaxLink link = (AjaxLink)linkComponent;
setupRequestAndResponse(true);
WebRequestCycle requestCycle = createRequestCycle();
callOnBeginRequest(requestCycle);
AjaxRequestTarget target = new
AjaxRequestTarget(link.getPage());
requestCycle.setRequestTarget(target);
link.onClick(target);
// process the request target
processRequestCycle(requestCycle);
This means that the link's onClick method is called before my request cycle
hooks have a chance to restore conversational state.
Is there an alternate way I should be hooking into wicket so that I can
reliably intercept requests to pages and retrieve/store metadata?
Thank you,
-Clint
